If you looking to trouble shoot or document your IP networks I recommend this tool from NetScout. Very handy to track down which switch and switch port your network cable is plugged into. Also has a free cloud reporting service to document your network installs so you have have multiple techs in the field with this and be able to review the results in real time back at your office. Keep in mind you need managed switches for this tool to work.
